Last Modified: 2014-05-15
I created hashmap as below

HashMap<String, String> h = new HashMap<String, String>();                          
h.put("xx", "156");
h.put("xx", "157");    
h.put("xx", "166");
h.put("yy", "176");    
h.put("yy", "179");

now if I want to know how many entries are there in the above hashmap for key "xx" what should I do...
so for above example the count for key "xx" is 3 and count for 'yy' is 2
